To all whom itmag concern: I

I Be it known that I, FRANK CL. HA nE -EY, a citizen .of the Unitedstates residin'g at John Day, Grant County,'in the State of Oregon, haveinvented certain new and useful Improvements in Wrenches, of which thefollowing is a specification. V

" This invention relates to wrenches. and

more particularly to an adjustable wrenchhaving a jaw which is slidableandja jaw which is pivoted, together with means for convenientlypositioning the slidable jaw with respect to the pivoted jaw and forholding the jaws securely and rigidly in'adjuste d position. The wrenchcomprisingi fthis invention may also belprovided with. aheadconstituting a semi-socket so thatv a bolt head, nutporthe like may begripped on four sides, and at the same time the aws constitutingthe headof thewrench are also designedso that ;the wrench may be used on roundobjects, such as bolts and the like,

'The main object ofthe invention is to provide a wrench having the abovementioned characteristicsand other objects of the invention will beapparent fromthe folloW- ing description and the'accompanying drawingsforminga part of this specification; ,In the drawings;

1 Fig. 5 is a sectional view on the line 5-5 reference characterdesignates the handle which maybe knurled as shown and provided .withthe finger grooves 11. Continuous with the handle 10 is a portion 12provided with a pocket 13"from Whichextends able :head 15 the shank 16of which is tapered as shown and having a plunger extension 17 receivedin the handle bore 14, a spring 18 mounted in the borebetwe'en the endthereof and the plunger 17 yieldingly pressing the head 15 axially ofthe pocketed member 12. The pocketed member 12 has a slot 19 throughwhich travels a pin 20 secured to the shank 16 whereby the head 15 maybe conveniently moved into a desired position against the spring 18. fThe pocketed member-12m provided with a lower earportion 21 to which ispivotally connected the head 22 by means of the pivot pin 23. The head22 has a'channelle'dshank' portion 24L which receives thehead15. Thehead 15 has the jaw p'ortion'25, andthe head 22has the jaw portion 26.The jaws 25 and26are constructed so as to constitute at their'lower endsa socket, each jaw being formed of two angularly disposed toothed orflat walls 27 and 28, the upper parts of the jaws having plane faceswith fiat or toothed surfaces as may be desired, these faces being.designated by the reference character 29 inFigs. 2. and 7 By this construction of the jaws, it is evident that the wrench may be used forbolt heads, nuts and the like, and also for round bolt shanks, pipes,and the like.

It will be obvious "that it is very easy to apply the wrench to thework, it being necessary only tomove" the head 15 by the pin 20 againstthe spring 18 until the jaws are wide enough to embrace the boltor nut,as the case may be, and then to release the pin 20 and permit the spring18'to forcethe head 15 against the work whereupon the head 15 may besecured in position by the means which will presently'be described.

The pocket 13 of the member 12 has two lower walls 30 and 31 which arearranged as shown preferably at right angles to each other, these wallsforming the outline of a recess into which is placed a tapering lockabove description.

ing key 32 operated by a screw 33, the key and screw being clearly shownby Figs. 2 and 6. The screw 33 passes through a threaded opening 34: inthe wall 31 and has a shoulder which bears on the face a, of the key 32to force the key into engagement with the tapered shank 16, and a ballpoint 35 which is received within a recess 36 in the key '32'to withdrawthe key from engagement with the shank when the head 15 is to bereadjusted. The surface 6 of the key 32 is at right angles to thesurface a, and the key is thus guided by the walls 30 and 31. lVhen thescrew 33 is turned to force the key 32 into engagement with the shank16, the surface I) of the key is guided by the wall 30, and inasmuch asthe wall 31 is at right angles to the wall 30 and parallel to thesurface a of the key, the pressure of the screw on the key is exertednormally of the surface a and maximum screw turning force is thusimparted to the key.

The construction and manner of manipulating the wrench is apparent fromthe In brief, the wrench comprises the pocketed member or housing 12,the slidable head 15, the pivoted head 22, andthe locking devicecomprising the key 32 and the screw 33. To adjust the wrench it isnecessary only to withdraw the key 32 from engagement with the shank, tomove the head 15 against the spring 18 until the jaws are properlyspaced, to place the jaws in position to embrace the work, releasing theslidable head to permit the spring to force it snugly against the work,and then to tighten the slidable head in position by turning the screw33 to force the key 32 into locking engagement with the shank 16. Fromthe drawings, it will be noted that there is a slight space 37 betweenthe shank 24 of the head 22 and the housing 12 to permit a small amountof free movement of the head 22 to take care of irregular sized bolts orheads, and also to permit of quick disengagement of the wrench from thework.

It is apparent that the wrench may be quickly applied and removed fromthe work and is very convenient in manipulation. By reason of the novelholding device of the slidable member, an adjustable wrench is providedand at the same time all the advantages'of a wrench of the fixed headtype are preserved. The holding device cannot be moved from adjustedposition except by v operation of the screw, and the greater the wrenchturning stress, the greater is the resistance offered by the holding keyto movement of the slidable head.

In view of my disclosure, certain changes in the construction andarrangement of parts may be made without departing from theinvention,and it is to be understood that this disclosure while being illustrativeof the best mode of embodying my invention is not to be considered aslimiting the inven tion thereto, but any changes that come within thescope of the appended claims are to be considered as partof thisinvention.

Having thus described my invention, what I claim and desire to secure byLetters Patent of the United States is:

1. A wrench comprising a stationary member having a longitudinal boreand a recess in communication with said bore, a longitudinally movablemember having a tapered shank slidable in said bore over said recess, ahead pivoted to said stationary member at a point below said taperedshank, a tapered locking key within said recess and cooperating withsaid tapered shank for holding the latter in rigid adjusted positionwith respect to said stationary member, and a screw bear ing on saidlocking key for holding same against said tapered shank.

2.
